Mullen says gay ban in military should be lifted

The military's top uniformed officer on Tuesday made an impassioned plea for allowing gays to serve openly in uniform, telling a Senate panel it was a matter of integrity and that it is wrong to force people to "lie about who they are in order to defend their fellow citizens."

The comments by Adm. Mike Mullen, chairman of the Joint Chiefs of Staff, set the stage for the Defense Department's yearlong study into how the ban can be repealed without causing a major upheaval in the military.

Defense Secretary Robert Gates, appearing with Mullen before the Armed Services Committee, announced plans to loosen enforcement rules involving the "don't ask, don't tell" policy that has been in effect since 1993.
